48 ====== **Required Data** ======
49 )))|A combination of satellite data for surface temperatures and data from monitoring stations or traverses for air temperatures offers the most complete picture of a city's heat island.

51 ====== **Expected Outputs** ======
52 )))|Urban area that is significantly warmer than its rural or undeveloped surrounding areas. Expressed and evaluated as temperature (°C).
53 |(((
54 ====== **Calculation methods** ======
55 )))|The Urban heat island temperature effect is calculated as: the daily average global radiation S, the maximum-minimum temperature difference ΔT. the daily average wind speed, measured at 10m above ground.
